In geometry, an equilateral triangle is a triangle in which aw three sides are equal. In tradeetional or Euclidean geometry, equilateral triangles are an aa equiangular; that is, aw three internal angles are an aa congruent tae ilk ither an are each 60°. Thay are regular polygons, an can tharefore an a be referred tae as regular triangles.
